This pressure limiting valve operates effectively within a temperature range of -40°C to +80°C.

Key Features & Benefits

This valve basically controls the maximum air pressure that gets to certain parts of your air brake system, specifically things like the spring brakes. It limits how much pressure builds up. It’s a pretty simple idea, but it’s crucial for safety. It can also act as a kind of safety net, preventing over – pressurization that could damage other components. Think of it like a gatekeeper for the air pressure. It’s typically installed between the air compressor and the air tanks, and then connected to the spring brakes and sometimes other systems. It's there to make sure no single part gets overwhelmed. It ensures everything stays within safe operating limits, even if your compressor is working a little too hard, or if there's a surge in pressure somewhere.

Symptoms, Risks & Replacements

It's important because those spring brakes are a big deal. They're your emergency brake, and you need them to work every time. If pressure gets too high, it can cause them to partially apply unexpectedly, or even fail completely. This valve protects against that. You’ll notice if this valve fails because your spring brakes might not hold properly, or might drag a bit. It's a key safety component, and keeping it in good working order is essential. You can often find replacements at places like Fixparts Online, and they aren't too difficult to swap out if you're comfortable working on air brakes.
